Climate - The climate in Idaho varies with the elevation. The bottom of Hell's Canyon, Boise and other locations at low elevations receive hot summer weather. Temperatures at these elevations often reach 90 degrees or more during the summer months. At the same time the mountains will get mild temperatures with cool nights.
Winters are just as extreme with the mountains experiencing extreme conditions and temperatures. An average of 500 inches of snow falls on the Idaho highlands. Temperatures are known to dip below zero degrees F on many winter nights. The lower elevations enjoy a more mild winter season with less precipitation than the mountains. The sun is a constant throughout the year. Be sure to wear sunscreen and layered clothing in Idaho's unpredictable weather.
